Denisse Escobedo, 31, was booked into the Dallas County jail late Sunday, jail records show. She is charged with a felony count of impersonating a public servant and misdemeanor counts of official oppression and failure to report a felony resulting in serious bodily injury.

According to an arrest-warrant affidavit, Escobedo, who works in the Precinct 5 constable's office, was hired with other law-enforcement officers to work security at a party in Pleasant Grove over the weekend and arranged for her cousin Ramiro Vielma III to fill in when one of the officers backed out.

Vielma, 39, who is not a peace officer, was wearing a black T-shirt with the word "POLICE" on the back, as was Escobedo, the affidavit says.

Around 12:30 a.m. Sunday, a gray GMC Sierra pickup truck with four men inside drove up to the entrance gate at the venue in the 2500 block of Lewiston Avenue and was stopped by Escobedo and a man in a lime-green vest.

According to the affidavit, Escobedo told the man to confiscate a case of Modelo beer from the driver, who is over the age of 21, and then refused to show him a badge when he asked to see one. She told him she'd ticket him for having an open container if he didn't leave, the affidavit says.

The driver told police he turned the truck around and that Escobedo and the man in the vest were shining flashlights at him and ordering him to stop. Not believing they were "real police," he slowly drove past them as they starting banging on his windows with a flashlight and gun, he said.

As he continued to drive, passengers saw Escobedo and the man in the vest reach for their guns and several shots were fired at the vehicle, the affidavit says. The driver was struck in the right ear, one passenger was hit in his left hand and another passenger was shot in his left shoulder.

In an interview with a detective, Escobedo said she didn't see who fired the shots and did not know who the man in the vest was, the affidavit says. She also said she only confiscated alcohol from people who weren't of legal drinking age.

Escobedo was put on administrative leave while police and the office conduct investigations, according to Precinct 5 Constable Michael Orozco.

Orozco said in a statement that his department and command staff "are fully assisting and cooperating with the Dallas Police Department."

Escobedo was released from custody after posting $3,500 bond, court records show.

Vielma, who was also charged with impersonating a public servant, was booked into the Dallas County jail and released after posting $1,000 bond.
